Canon has expanded their mirrorless lens lineup by two lenses, the RF 85mm f/1.2L USM DS and RF 70-200mm f/2.8L IS USM. Both lenses are unique in their own ways. Check them out!
RF 70-200mm f/2.8L IS USM
The RF 70-200mm f/2.8L IS USM completes the f/2.8 zoom holy trinity alongside the RF 15-35mm f/2.8L IS USM and RF 24-70mm f/2.8L IS USM lenses. It's a bit unique in that it is not internally zooming. This makes it quite short when used at the wide end, though it does become physically longer as you zoom in. In terms of weight, the RF 70-200mm f/2.8L IS comes in 28% lighter than its EF cousin, however, which will be a nice step forward for any photographer who makes their living with a 70-200mm lens (wedding photographers, for example). The weight distribution has also been improved, concentrating more of the elements closer to the camera body, improving balance.
The new lens is the first Canon lenses to include two Nano USM focusing motors, likely making it very quick to focus. Each motor drives a separate lens group as part of a floating focus control, reducing focusing distance and breathing. In addition, the lens includes Canon's customizable control ring, 17 lens elements in 13 groups, including two aspherical elements, four UD elements, and one super UD element, five stops of image stabilization, dust and weather resistance, and Subwavelength Structure Coating to reduce flare and ghosting.
RF 85mm f/1.2L USM DS
The RF 85mm f/1.2L USM DS is a variation on Canon's most famous portrait lens design, including defocus smoothing, which is Canon's term for apodization. This produces especially smooth bokeh. The tradeoff with this is that the lens loses around 1-1.5 stops of transmittance, effectively making it somewhere around a T2-T2.2 lens, as is standard with such lenses. This means you'll have the depth of field properties of an f/1.2 lens, but the light-gathering abilities of an approximately f/2 or f/2.2 lens.
In addition, the lens features Canon's customizable control ring, one aspherical element, one UD element, blue refractive optics to reduce chromatic aberration, dust and weather resistance, and Air Sphere Coating to reduce flare and ghosting.
